SPECIFICATION forming part of Letters Patent No. 431,805, dated J'u1y 8, 1890. Application filed December 29,1888. Serial No. 294,921. (No model.)

To all whom it may concern.-

Be it known that I, OTIS C. ELLIOTT, of Quinsigamond, in the city and the county of \Vorcester and State of Massachusetts, a citi- 5 zen of the United States, have invented a new and useful Improvement in Horseshoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Calked horseshoes as ordinarily made present several features which are objectionable. The heel-calks'are usually turned down out of iron and the toe-calks are welded on from r steel. At the time when it is desirable to use calksnamely, in icy or snowy weatherun- -less the shoe is made on its inner edge witha bevel from above downward and outward, the foot is apt to ball, as it is called, and the advantage of the calking is'thus destroyed or lessened. In addition to this, the calksget blunt, and when blunted the shoe requires to be removed to sharpen them, frequently on' hard-working horses, in the season of snow and ice, as often as once in two or three days, to keep the horse reasonably sharp shod. This is particularly the case on the stone pavements of large cities with the horses used in public trafficsuch as on street-cars, oninibuses, express-wagons, job-wagons, and public carriages. Detachable calks have been used, and to keep them sharp they have been made with steel centers and iron exteriors and screwed into the shoe; but when used with ordinary 5 shoes this method has presented some difliculties which it is the object of the present invention to remedy.

In the drawings, Figure 1 is a perspective of a forward shoe intended to be used with a 40 detachable calk and to obviate most, if not all, of these defects.

The hoof-surface of this shoe is made level from the outside to the inside instead of, as usual, beveled about half-way toward the in- 5 terior of the shoe, so as to leave aspace between the sole of the foot and the shoe all along the inside edge of the shoe, in which the snow and ice may rivet itself, as it were. This formation of the hoof-surface of the shoe is not novel. The ground-surface of the shoe is rounded over from the inner edge toward the outer edge, making it nearly, but not quite, a quarter-cylindrical surface on the branches of the shoe, and is still more rounded on the outer margin at the toe. The fullering-crease is put in in the usual way near the outer margin of the shoe. There are two toecalks and two heel-calks to this shoe, and each of the calks has a calk-seat, which is raised above the general ground-surface of the shoe 6o and is level on top. Through the center of this calk-seat is drilled a hole, into which the shank of the calk is set. The interior of this hole may be made as a nut, and the shank of the calk maybe made as a screw, if desired; but I prefer the construction shown in Sheet 2 of the drawings, where the shank of the calk is smooth and the interior of the hole is smooth, and the calk is held in place bya setscrcw s,'Figs. 2, 5, and 7, driven in through the edge of the shoe so as to impinge against the shank of the calk and clamp it firmly in place.

It is frequently desirable in opening the gait of speedy horses to use toe-weightsand side-weights to the shoes, and yet it is desirable that these weights should not be such as to tire the horse, particularly if a road horse,

and make him leg-weary. A comparatively small difference of weight on the bottom of the foot will produce the desired result of opening the gait as well as, if not better than, the larger weight strapped upon the side, and interferes less with the action of the foot. The necessary preponderance of one side of 8 5 the foot over the other can be produced with-, out increasing the ordinary weight of the shoe by reducing the weight of one side of the shoe and increasing the weight of the other side of the shoe, and in case shoes are made which employ these detachable calks and have the necessary calk-seats, such a shoe may be reduced at the side to hardly more than is necessary in width for the fullering-crease and at the toe to just enough 5 iron to connect pretty stitfiy the calk-seats and branches of the shoe to each other. This part of my invention is shown in the draw ings on Sheet 2.

A is the toe of the shoe. It may be wide :00

and strong, as shown in Fig. 1, or it may be reduced in width, as shown in Fig. 4 of Sheet 2. In either case it is slightly rounded there as if a part of a cylindrical ring, as shown in the drawings. This prevents the shoe from balling at that point. At either side of the toe A are the calk-seats B, somewhat raised above the level of the shoe, which is gradually sloped up toward them, and having a flat upper surface for the calk-seat proper, as shown at O. This calk-seat proper is drilled through at its center, as shown at D. The calk is made either, as shown in Fig. 3, as a cone F, mounted on the cylindrical stem E, or as a conoidal figure F, as shown in Figs. 4, 5, and 6. The conoidal figure is mounted upon the same stem E as the conical figure. The conoidal figure presents the advantages of a somewhat slimmer and taller calk of about equal strength; or if of the same weight as the conical-pointed calk it would be better in light work. The branches of the shoe G are thickest at their outside edges and continue about an equal thickness until after the fullering-crease has been passed, and then are.

curved in a convex curve to the inside edge of the branches, and they terminate at the ends in calk-seats H H, as shown in Fig. 1. In 1-1, Fig. 1, is a calk-seat perforated before the calk is applied. The calk itself is shown in Fig. 3, and a section of the calk and calkseat at the line w 00 of Fig. 1 is shown in Fig. 2 somewhat enlarged.

In the drawings on Sheet 1 the detachable calk is shown as applied in the usual waynamely, with a screw-shank-but in the drawings on Sheet 2 it is shown as applied with theaid of a set-screw S, Fig. 7, driven onto the shank from the outside, and the use of a set-screw is desirable even when the calk is provided with a screw-shank. By this use of the set-screw to fix the shank of the calk in place I am enabled to use calksof other crosssections than the circular cross-section-as, for instance, I might use a wedge-shaped calk to advantage.

. The things which I believe to be. novel in this invention are the calk-seats, combined with the branches and toe part of a shoe of different contour from the surface of the calkseat, the application of the set-screw, in combination with such calk-seats for fastening the shank of the detachable calk in place, and the shoe with differential sides for the purpose of doing away with toe-weights.

I have found that a shoe made of this general pattern, but without detachable calks, and even without perforated calk-seats, has all the advantages of an ordinary calked shoe, and greater simplicity, strength, and durability, and a nice finish.

I claim as my invention and desire to se cure by Letters Patent of the United States- 1. The combination, in a horseshoe, of branches having a thick outer edge, a level foot-surface, and a convex ground-surface uniting at the inner end of the branch with the hoof-surface, with raised calk-seats having alevel lower surface of the size and shape of the bottom of the calk and perforated in the center to receive the shank of a detachable calk, and a toe part having a flat hoofsurface and a convex ground-surface, substantially as described.

2. The combination, in a horseshoe, of a calk-seat having a fiat calk-bed resting upon a wall somewhat elevated from the groundsurface of the shoe and of the same plan as the bottom of the calk, which said calk-seat is pierced in the center at D for the passage of the shank of the calk, with a detachable calk formed with the shank E to fit the hole D, and in further combination with the setscrew 8, driven through the Walls of the calkseat and impinged against the shank of the calk, substantially as described.
